Lore

Originally the Gondorian province of Calenardhon, the land north of the White Mountains was gifted by Steward Cirion to Eorl of the Northmen in 2510 (Third Age). Eorl had led his men through great hardship from the far north to the aid of Gondor, and Cirion gave him the wide green lands of Calenardhon in recognition of his aid, swearing eternal friendship between old Gondor and the new land of Rohan.

Nonetheless, the line of the Kings of Rohan stretched from Eorl's time to the War of the Ring and beyond. The Kings sat in the Golden Hall of Meduseld in Edoras, built by Eorl's son Brego. At the time of Gondor's greatest need, they kept the Oath of Eorl, and rode to the aid of their ancient allies at the Battle of the Pelennor Fields.

Areas

There are six areas in the East Rohan Region. Many players skip Eaves of Fangorn even though the questline leads to it first before Sutcrofts. Some players simply go to the Garsfeld Mead Hall and continue working on reputation granting quests.

It is necessary to complete all the non-optional quests to get one's first War-steed.

This quest arc is the same if you begin your exploration of Rohan as a result of a mail message from "G." -- Rohan Awaits, or a mail message from Galadriel: "A Need in Rohan." (Which begins Volume III, Book 7 of the Epic Quest line.)

In this quest arc, you will encounter new game technology -- three "Landscape Quests." That is, quests you acquire by virtue of your being in a certain location. A "Quest Action" button pop-up appears on your screen to announce the availability of landscape quests.

Quest Sequencing - When entering Rohan via Volume 3: Book 7 Chapter 6: A Journey by Boat
the Epic quest line interweaves with multiple "local" Quest Hubs.
While not necessary to complete any of these "local" quests to follow the Epic line and to move on to obtain one's Warhorse, they do afford experience roughly equal to 1.5 levels if all are completed.

An Unusual Migration
This series of quests begins with a Landscape quest as you approach Rook sitting beside the Entwade, due WEST of the Skirmish camp outside Snowbourn. [60.0S, 63.5W] They can be done at any time.
